OK that wasn't really thought through. Because I changed the design
mid-way through writing it __callerclass__ wasn't doing the right
thing. I've sorted the issues I could see and made it (hopefully)
thread-safe. I'm not going to pollute this list again with my code so
I've put it at the following address:

The problem is that all normal functions need to be decorated with
'@function' for it to work completely: if I understand correctly the
snippet below should raise an exception.  It only does so if 'f' is
decorated with '@function' as below.

----------
@function
def f(x):
    x.l()

class C(Object):
    @localmethod
    def l(self):
        print "Shouldn't get here"
    def v(self):
        return f(self)

C().v() # Raises LocalMethod exception
----------

PS: in fact I'm not sure it's a good idea to decorate local methods:
what about local attributes which are not methods? They have to be
treated differently as only functions can be decorated.

What about functions / classes which are local to a module?
